  If you have a table (db.mytable) that needs full revision history you 
  can just do:
<pre class="literalblock">
   form=crud.update(db.mytable,myrecord,onaccept=crud.archive)
</pre>
  <p>crud.archive will define a new table &quot;mytable_history&quot; and 
  store the previous record in the newly created table including a 
  reference to the current record.</p>
  If you want to access such table you need to define it yourself in a 
  model:
<pre class="literalblock">
   db.define_table('mytable_history',
       Field('current_record',db.mytable),
       db.mytable)
</pre>
  Notice such table includes all fields of db.mytable plus one: 
  current_record. crud.archive does not timestamp the stored record unless 
  your original table has a fields like:
<pre class="literalblock">
   db.define_table(...,
       Field('saved_on','datetime',
            default=request.now,update=request.now,writable=False),
       Field('saved_by',auth.user,
            default=auth.user_id,update=auth.user_id,writable=False),
</pre>
  <p>there is nothing special about these fields since they are filled 
  before the record is archived.</p>
  If you want to change the history table name and the name of the 
  reference field you can do, for example:
<pre class="literalblock">
   db.define_table('myhistory',
       Field('parent_record',db.mytable),
       db.mytable)
</pre>
  and use it as:
<pre class="literalblock">
   form=crud.update(db.mytable,myrecord,
                    onaccept=lambda form:crud.archive(form,
                    archive_table=db.myhistory,
                    current_record='parent_record'))
